Adjusting Valves

I want to adjust my valves soon and I cant seem to find any specs on here. Do any of you guys know what they are? Also, does the engine have to be warm, cold, or it doesnt matter.

IT MATTERS, the engine should be cold. You'll be sweating your ***** if you do it hot. It takes hours for that engine too cool down too. I think it'd be more acturate if it's cool too.

So whenever you put the feeler gauge in between the valve do you want the rocker to barely be touching or does ther need to be some pressure. So basically do you need to be able to slide it out easily when finish with adjusting?

You are asking for a opinion there, we'll probably all argue on that one. I like it tight.............along with other things.

First off ALWAYS lash the valves on a COLD motor.......

You want to make it so the gauge is snug ..... the specs call for 10 on the intake and 20 on the exhaust ....... I run mine 8 and 18 ..... now I dot recommend everyone do this, I have a cam and I have mine setup for a race application. I do drive mine 500+ miles a week.

ditto on what twisted shifter said. There have been some companies that recommend hot lash settings, but they are few and far between and I do not believe you will come across them in this industry. In general, stick with cold settings on our engines.

There is a way to double check your settings on your lash. It easy... If it need to be .010 then a .011 should NOT fit... Same goes for the .020 then .021 should not fit...

All engines I've every worked on require COLD adjustment...
